TWO:256"I don't know what has been said, Major, but something more than just what's in the papers must have gotten about. That sort of mud-slinging is too common to cause comment, even. It must be some spite work. There's no reason to suppose, surely, that after a quarter of a century of gallant service he's been and shown the white feather. He's awfully cut up, really he is. He's noticed it, of course, and it's too deuced bad, kicking a man when he's down sick and can't help himself."

Membrane separation type solvent dehydration system

Great attention is recently being paid to global environmental issues, and it is now conceivable that companies will need to treat used solvents themselves. In consideration of this kind of social issue, we have developed a “membrane separation type solvent dehydration system,” which uses a polyimide membrane with superior dehydration properties developed by Ube Industries, Ltd. in combination with our own distillation and concentration technology that has resulted in solvents being more easily recovered.

THREE:
  • 1Under the distillation system, even in case of azeotropic solvent compositions, this system which remove water vapor by the polyimide membrane will easily dehydrate.
  • 2In comparison with the distillation system, it significantly saves on use of steam.
  • 3Dehydration can be performed through merely supplying evaporated vapor to the membrane module and maintaining the differential pressure between the permeable side and the impermeable side.
  • 4Solvent purity of 99.9% or more can be achieved by carrying out dehydration with a polyimide membrane only.
  • 5The polyimide membrane has superior heat and solvent resistance. Therefore, the vapor permeation system reduces contamination of the membrane and thus extends its life.
THREE:He helped her out. "I have drifted in a way," he went on to explain. "I left home when I was a mere boy, and the spirit of savagery and unrest laid hold of me. I can't break away. And I'm not even sure that I want to. You, I dare say, can't understand." Yet he felt so sure, for some reason, that she could that he[Pg 71] merely nodded his head when she said briefly, "I can." "Then, too," he went on, "there is something in the Indian character that strikes a responsive chord in me. I come of lawless stock myself. I was born in Sidney." Then he stopped short. What business was it of hers where he had been born? He had never seen fit to speak of it before. Nevertheless he intended that she should understand now. So he made it quite plain. "Sidney was a convict settlement, you know," he said deliberately, "and marriages were promiscuous. My grandfather was an officer who was best away from England. My grandmother poisoned her first husband. That is on my mother's side. On my father's side it was about as mixed." He leaned back, crossing his booted legs and running his fingers into his cartridge belt. His manner asked with a certain defiance, what she was going to do about it, or to think.

The aromatic polyimide membrane is highly permeable to water vapor but less permeable to vapors of organic compounds such as alcohol etc.

THREE:Larry, too, saw a number of difficultiesperhaps more than did Jeff, because, from Larrys point of view, due to Sandys suspicion of the superstitious pilot, Jeff must not go free with the gems in his pockets, nor did Larry dare be the one to go. If he did, Jeff might be playing a trick, let him get beyond chance of return in time, use some reserve gas and fly away.Dick pounded after the woman.
  • 1 Recovery of the detergent solvent Recovery of the cleaning solvent such as electronic parts industry, precision instrument industry.
  • 2Solvent recovery and the refinement Solvent recovery and the refinement such as chemical industry, an industry of medical supplies, food industry, the fermentation industry.
THREE:Why not?

Acetone, ethanol, methyl ethyl ketone, butanol, isopropyl alcohol, ethyl acetate, methyl isobutyl ketone, others (including hexane and toluene).
